Warner, 1510 Locust St., Sterling, Ill. 61081 Filed Oct. 22, 1965, Ser. No. 501,975 7 Claims. (Cl. 16-191) The present invention is concerned with a hinge and, more particularly, to a hinge having'means for limiting movement between the leaves of the hinge and, correspondingly, between elements to which the leaves may be attached.

Various hinge mechanisms have been heretofore proposed for controlling or limiting the relative movement of two elements, such as a `door and jamb, between which the leaves of a hinge may be connected. In a number of such prior art proposals, the hinge mechanisms have been somewhat complex or did not lend themselves to large scale production.

Accordingly, it is a primary object of this invention to provide an improved hinge mechanism for limiting the relative movement between the leaves of the hinge.

Another object is to provide a hinge mechanism of the fore-going type which lends itself to large scale production and may be readily assembled and adjusted as required.

These and other objects will be more apparent from the attached drawings and the following detailed description ofthe hinge and its operation.

In the drawings:

FIGURE 1 is an exploded view showing the basic elements of the hinge of the present invention.

FIGURE 2 is an elevation of the assembled hinge at tached to a door and associated jamb.

FIGURE 3 is a View similar to FIGURE l, partly in cross section, of the assembled hinge attached to a door and associated jamb.

FIGURE 4 is an elevation of the assembled hinge, partly in cross section, illustrating the operation of the hinge elements upon relative movement of the door with respect to the jamb.

FIGURE 5 is a view taken along line 5-5 of FIG- URE 1.

FIGURE 6 is an elevation, partly in cross section, of a modification of the hinge.

FIGURE 7 is an elevation, partly in cross section, of a further modification of the hinge.

Referring to FIGURE 1, the numerals 10 and 11 designate the leaves of the hinge, with leaf 10 being normally attached to the door jamb I and leaf 11 attached to the door D. Leaf 10 is provided with three vertically-spaced hollow cylindrical knuckles 12, 13 and 14, while leaf 11 is provided with two complementary or alternating hollow cylindrical verticallyspaced knuckles 15 and 16 which, in assembled position, form a tubular bore.

As indicated in the drawing, each of the knuckles 12 and 14 attached to leaf 10 are provided with a set of threads 18 and 19, respectively. so that they are counteracting on the opposite ends of a two-part pintle employed to unite the hinge leaves, as further described hereinafter.

Still referring to FIGURE l, the pintle for the hinge is composed of two telescoping sections 20 and 21. Each of the pintle sections is provided near its outer end with a set of counter pitched threads 22 and 23, respectively, for cooperative engagement with the aforementioned corresponding threads 18 and 19 of knuckles 12 and 14.

For purposes of securing the pintle in position within the assembled hinge and controlling its operation, each pintle section is provided with a cap, such as caps 25 and The threads are formed 26. The caps are attached to the end of each pintle section extending beyond the knuckles by means of a screw 27 and, in addition, may be further secured and prevented from turning on the pintle sections by use of longitudinally extending serrations 29 formed on the outside of the pintle ends for cooperation with corresponding serrations disposed on the inner periphery of the caps.

Each of the caps has, as an integral part thereof, a depending bifurcated collar 30 adapted to t over the associated edge of the hinge leaf 11. In order to permit the collar 30 to engage the hinge leaf as described, a small recess 31 should be provided in the door in the area immediately adjacent the point where the collar will engage the edge of the hinge.

The upper pintle section 20 has its lower portion 32 formed as a cone. The opposing end of the lower section 21 of the pintle is provided with a conical recess 33 adapted to receive the conical portion 32 of pintle section 20.

To install the hinge of this invention, lea-f 11 is attached to the door D and leaf 1@ attached to a jamb I. The door is then moved into position adjacent the jamb and knuckles 15 and 16 are disposed within the spaces between knuckles 12, 13 and 14 of leaf 10. When the knuckles are in alignment, a vertically extending tubular opening is formed in the usual manner by the knuckles adapted to receive the pintle sections.

To complete the assembly, pintle section 2@ is inserted into knuckle 12, conical portion 32 rst, until threads 22 have made contact with threads 18 on the interior of the knuckle. At this point pintle section 22 is then rotated to engage the complementary threads causing it to move further down into knuckle 12 with the lower end of conical portion 32 extending generally into knuckle 13. Nonnally, the cap for a pintle section will remain separated until after the section is in its desired position. If the cap is should be loosely connected so as to permit free rotation of the pintle section in the knuckles. After pintle section 20 has been inserted into the tubular bore to the desired extent, cap 25 may then be firmly attached in position by means of screw 27 with the bifurcated collar 30 disposed over the associated edge of hinge leaf 11 as further illustrated in FIGURE 5.

Pintle section 21 may then be similarly installed within the hinge knuckles by engagement of threads 23 with threads 19 of knuckle 14. As indicated, the cam action of threads 19 on complementary threads 23 of pintle section 21 is counter to that of the analogous threads on knuckle 12, whereby, rotated in the same direction, conical portion 32 can be telescoped intorecess 33.

Neither pintle section is inserted into the` knuckles to the full extent possible but only partially so as illustrated gitudinal or telescoping movement, as further described hereinafter, to control operation af the door. Thus, as in dicated in FIGURE 2 an appropriate distance X and Y, respectively, is retained between the cap and knuckle for each pintle section to permit further inward movement of each pintle section and, correspondingly, telescoping of conical section 32 into recess 33.

In operation of the embodiments of the hinge assembly described and disclosed in FIGURES 1-5, the door D is normally moved toward a right angle position with respect to jamb J or the wall surface of which the jamb is a part. Hinge 11 and its associated knuckles 15 and 16, being attached to the door, move with and in the same plane as the door, the `door D and the attached hinge leaf the manner described, the connection between the caps attached to the section during installation, it

when the two pintle sections are 25 and 26 and the hinge leaf 1i by means of collars 30 causes the two opposing sections of the pintle to rotate and move inward toward one another due to the counter cam-like action of the threaded sections 22 and 23 of the two pintle sections vwith the corresponding threaded sections 18 and 19 of knuckles 12 and 14. Under the force thus exerted on the pintles through the cam threads, they are permitted to move toward one another until conical portion 32 of pintle section 20 is stopped by the sides and bottom of recess 33 of pintle section 21. At this point further movement of door D with respect to jamb J is prevented. Collars 30 are bifurcated to the extent that they can move inwardly over the edges of the hinge to the extent necessary as the caps are carried inwardly with the pintles. The change in position of the collars as the door is `moved is best illustrated by comparing their positions in FIGURES 2 an-d 4.

The relative movement between hinge leaves and 11 and thus the amount of rotation of door D can be controlled by the extent to which the two pintle sections and 21 are initially inserted into the bore formed by the knuckles. If a relatively wide angle movement of the door is desired, the two pintles will be threaded into knuckles l2 and 14 to only a minimum degree. However, if a relatively small angle of movement of the door is preferred, the pintles will be initially installed and rotated in their respective threaded knuckles until only a small distancepseparates the conical portion 32 of pintle 20 from the sides of recess 33 of pintle 2l. Upon reverse movement of the door and leaf Il, the two pintle sections will, of course, move in the opposite direction and away from one another.

In FIGURE 6 there is shown a modified construction wherein the telescoping portions of the pintles are cylindrical rather than conical. Thus, pintle 40 is provided with a cylindrical recess 41 adapted to receive a cylindrical rod-like extension 42 of pintle 43. Operation and control of the modification illustrated by this ligure is the same as that described above. Y The modification shown in FIGURE 7 consists of two pintle sections 50 and 51, both of which are provided with opposing recesses 52 and 53, respectively, rather than complementary telescoping elements. Disposed in and extending between the opposing recesses is a spring 54. The spring is of the compression type and will serve to limit the longitudinal travel of the two pintle sections in a somewhat similar manner as contemplated for the other modifications previously described. However, the use of a spring also provides cushioning for the hinge assembly thereby preventing damage to the assembly which might result from the use of excessive force in opening a door.

While certain presently preferred embodiments of the invention have been described, it is understood that additional modications could be made within the concepts disclosed and claimed. Further, it will also be appreciated that the basic mechanism is appropriate for controlling relative movement of elements other than a door.
